Emergency presentation of colorectal cancer in Africa: a scoping review.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis review identified and mapped the current evidence on emergency presentation of colorectal cancer in Africa.
designScoping review based on methodology by Arksey and O'Malley. DATA SOURCES: Medline (via PubMed), Embase and African Journals Online were searched between 29 January 2025 and 6 March 2025. ELIGIBILITY CRITERIA: Studies published in English and describing the burden, risk factors and management options for emergency presentation of colorectal cancer in Africa were included. Full-text articles of all epidemiological study designs were considered with no publication date limit. Grey literature such as conference abstracts and letters to the editor were considered if sufficient study detail was provided to map data to the research questions. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data from the included studies onto a standardised electronic form. Data were narratively synthesised using predefined themes.
resultsTwenty-seven studies are included in this review. There was wide variability in reported emergency presentation colorectal cancer rates (8.3% to 64.9%). There were few data on early mortality, and none on long-term outcomes following surgery for colorectal cancer. Emergency presentation of colorectal cancer was characterised clinically by bowel obstruction, bowel perforation and peritonitis. Only one study reported on risk factors for emergency presentation of colorectal cancer. Use of diagnostic modalities was variable and depended on resource availability. Surgery was the mainstay of treatment. Endoscopic stenting was only available as a treatment option in South Africa.
conclusionsEmergency presentation of colorectal cancer is a significant clinical, oncological and health system metric, yet there is a dearth of evidence on the subject in the African context. Available evidence demonstrates the need for more studies on emergency presentation of colorectal cancer, focused on risk factors, prevalence, treatment options and short-term and long-term outcomes.
